The subtractive color model is the basis for color printing, color photographic prints, 
and transparencies. While the additive color model simulates the visible spectrum of 
color by adding light of three primary hues, the subtractive color model starts with a 
“white” or neutral light source containing light of many wavelengths. Inks, toners, or 
other 

 are used to selectively absorb (subtract) certain wavelengths of light 

that otherwise would be reflected or transmitted by the media in use. 

The 

 are cyan, magenta, and yellow; they absorb red, green, and 

blue light, respectively (as shown in the following figure). Combining any two 
subtractive primaries creates a new color that is relatively pure or saturated. For 
example, you can make red by combining magenta and yellow, which absorb green and 
blue light, respectively. White occurs when no colorant is applied. In theory, 
combining all three subtractive primaries yields black, but due to deficiencies of cyan, 
magenta, and yellow colorants, combining these three primaries actually yields a 
muddy brown. Black colorant is added to compensate for the deficiencies of cyan, 
magenta, and yellow colorants. Consequently, color printing uses four 

yan, 

agenta, 

ellow, and blac

). The use of black toner produces rich, 

solid blacks and allows for improved rendering of black text.
